UNITED STATES CHARLES O. MILLER, OF FORT WAYNE, INDIANA.

Application led August 16, 1926. Serial' 11o. 129,851.

The invention relates to boxes and particularly to the two piece collapsible type formed of paperboard.

In the two piece paperboard box generally in use at the present time, each part is received by the user in collapsed form and he must set it up before using. The setting up process is relatively a slow one since, as a general rule, the sides and ends of each part must be turned up and the locking tongues on the ends must be engaged inV slots in the sides or vice versa.

The object of the present invention is to provide a novel collapsible paperboard box in which the parts may be set up with great rapidity and with little effort, and providing maximum strength.

' An embodiment of the invention yis illustrated in the accompanying drawings, in which Figure 1 is a perspective view of the box in closed condition; Fig. 2 a plan view of one of the fully collapsed parts of a two-piece box; Fig. 3 a' plan view of the same in partially collapsed condition for shipping or storage; Fig. 4 a side elevation of the part in condition for setting up; Fig. 5 an enlarged plan view of the part fully set up and Fig. 6 is a fractional plan view of thepart set up, the locking means being shown in horizontal section.

In the illustrative embodiment of the invention, the box consists of two pieces, preferably similar in construction and adapted to form a container section or part 1 and a cover section or part 2. The two parts being similar it is only necessary to describe one of them.

The blank 3, from which either the receptacle portion or cover portion of the box is formed, consists of a sheet of suitable material, preferably paperboard, that is scored at 4, 5, 6 and 'Z to form a lateral wall 8, ,which forms the bottom of the container or top ofthe cover. Scorings 9 and 10 cooperate with the scoring f1 to form a side wall 11 and the scorings 12 and lcooperate with the scoring .45 6 to form a side wall 14. The board is scored and perforated at opposite ends of each scoring 4 and 6, the line of perforations and scoring 15 cooperating with the scoring 9 to form a corner section 1.6, corner section,17 being defined by the scoring 12 andthe line of perforations and scoring 18, corner section 19 being dened by the scoring 13 and the line of perorations and scoring 20 and the corner section 21 being dened by the scoring 10 and the. line of perforations and scoring 22. Each corner section is scored along a diagonal line and perforated in said scoring as shown at 23, upon which diagonal perforated scoring each corner section will collapse or fold.

The material is also transversely scored at 24 and 25 parallel to the scorings 5 and 7 respectively to form the end wall sections 26 and 27, and to form the extensions or flaps 28 and 29. Tabs 30 and 31 are formed along the outer edge of the extensions or flaps respectively. uitable abutments are formed on or secured to the section 8 adjacent to the scorings 5 and 7 such as strips 32 that are secured to said section. Any form of abutment that l will project from the surface of the sect-ion 8 will sulce.

The side Walls 11 and 14 are turned over onto the section 8, the corner sections folding j onto the end sections 26 and 27 simultaneously therewith. The flaps 28 land 29 are then turned over onto the corner sections and the end sections as shown in Fig. 3. In this condition the parts are packed in bundles and shipped to customers or stored. Whenone of the parts is released from a bundle or pile the side walls rise, the corner sections expand somewhat as shown in Fig. 4 and in dotted outline in Fig. 5, and the laps rest against the edges of the corner sections. The perforated scorings 15, 18 2O and 22 break down the resistance of the board and permit the corner sections to remain folded more or less inwardn ly. With the part in the condition shown in Fig. 4, the user places his hands under the end sections 26 and 27 and raises the entire part. This movement swings the end sections upwardly, the corner sections readily collapse and the aps 28 and 29 fold over the collapsed corner sectionsand the tabs engage behind the abutments 32, the simple movement of the end sections to a vertical position causing .the closing of the ends of thepart and the locking of the walls to the transverse wall-the bottom or top of thepart.

In other words, the user sets up the box b merely raising the ends of each part to a vertical position, this being accomplished with great rapidity and ease. The perforated scormg at the eoterminal line of each corner section and the adjacent wallsection, together 'with the diagonal perforated scoring in each corner section and the rounded edge of the latter section, permit the said corner sections to freely collapse or'fold inwardly as the end sections are moved upwardlyand said corner sections, being relatively st' y connected to the side walls, cause the latter walls to move to `aA vertical position as the end sections are moved upwardly so that the flaps on the end walls swing over the colll sed corner sections to a vertical position with1n the part, the low er edge of each preferably engaging the bottom or top of the part, as the case may be, and the tabs bending horizontally into engagementwith the abutments..
